SEAL.

To all whom, it may concern Be it known that I, EMIL TYDEN, a citizen of the United States, residing at Hastings, in the county of Barry and State of Michigan, have invented new and useful Improvements in Seals, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

The purpose of this invention'is to provide an improved construction of seal of the sort comprising soft metal which is clenched onto a securing wire or cord.

It consists in the elements and features of construction shown and described as indicated in the claims.

In the drawings: Figure 1 is a perspective view of a seal embodying this inven tion, securing the ends of a knotted cord. Fig. 2 is a section of such seal made transversely to the path of the cords therethrough. Fig. 3 is a plan view of a sheet metal blank of hard metal on which the soft metal portion of the seal is secured, showing said blank formed preparatory to molding or casting the soft metal thereon. Fig. 4 is a view similar to Fig. 2 showing a modification in respect to the form of the hard sheet metal element when the seal is to be adapted to securing a relatively slender wire instead of cord. Fig. 5 is a plan View of the hard sheet metal blank employed in the form of a seal shown in Fig. 4. Fig. 6 is a plan view of a seal of the general character shown in the other figures, but modified by providing the sheet metal element with a tag strip or lug. Fig. 7 is a perspective view of the blank shown in Fig. 3 with the lugs struck up therefrom and bent in the form in which they are found in the finished seal. Fig. .8 is a plan view of the blank from which is formed the hard sheet metal element of a modified form of seal. Fig. 9 is a section of seal of such modified form taken at the plane indicated by the line, 9, 9, on Fig. 8. Fig. 10 is a section of the same taken as indicated at the line, 10, 10, on Fig. 8.

The seal shown in the drawings comprises a hard sheet metal element, 1, upon which soft metal bosses are formed by casting or molding the soft metal, the hard-sheet metal disk having first had struck up from it lugs which are embedded in the soft metal of said bosses in form and position adapting them to be pressed by the clenching of the Specification of Letters Patent.

soft metal bosses onto the securing cord or wire, and most preferably so that said lugs of the hard metal will wholly or partially encompass and engage the cord or wire. In all the forms shown soft metal bosses are formed upon opposite sides of the hard metal disk, and the securing cord or wire isextended through both the bosses so that the hard metal disk is between two strands of such cord or wire.

In the form shown in Figs. 1, 2 and 3 in which the bosses, 2, 2, are large enough so that their apertures, 3, 3, may accommodate a comparatively heavy cord inserted through said apertures, the hard metal element or disk, 1, has struck up from its middle portion lugs, 4, 4, and 5, 5, a lug, 4, and a lug, 5, projecting at one side and the other lug, 4, and the other lug, 5, projecting from the opposite side of the disk. Preferably all four lugs are struck up out of and result in forming a single aperture, 6, in the disk, 1. The met-a1 struck out of the aperture being severed at three parallel lines to form the four lugs, each lug being long enough to be bent so as to overhang the cord aperture which is to be formed in the soft metal boss, one lug at each side of the disk overhanging the cord aperture in the boss at that side from one side of said aperture and the other lug at that side of the disk overhanging the aperture from the opposite side thereof so that the cord aperture and the cord when therein, is completely guarded by the hard metal of the lugs forming or lying immediately back of the surface of the aperture. From this construction it results that when bosses, 2, 2, of soft metal are cast or molded upon the opposite side-s of the hard metal disks occupying the aperture, 6, and when cord apertures, 3, 3, are formed through these lugs, there is embedded in each boss alug, 4, and a lug, 5, tip-standing at opposite sides of a cord aperture and over-hanging that aperture so that when the boss is clenched down upon the cord, the hard metal lugs are also folded down upon the cord and may be engaged therewith, and in any event by their stiffness render the engagement more secure than would be the engagement of the clenched soft metal bosses alone. Preferably the margin of the hard metal disk, 2, is hemmed, that is folded inward and clenched upon itself at one side as shown in Fig. 2.

In the form shown in Figs. 4 and 5 the soft metal bosses, 2, and the apertures, 3, are smaller than in the preceding figures because the apertures are designed to accommodate relatively slender wire employed for securing the seal, or a package to which the seal is attached. In seals designed for this mode of use, the lugs of the hard metal disk to be embedded in the soft metal bosses can be formed in staple-like fashion, that is, being struck up and stretched out of the sheet metal without severance of the portion of metal thus struck up. Such staple-like lugs, 9, 9, are struck up one each way out of and forming an aperture in the sheet metal, as seen in Fig. 5. And the apertures, 3, 3, through the bosses extend through or under said staple-like lugs so that the latter encompass the wire and so that when the bosses are clenched or crushed down upon the wire, the staple-like lugs are also clenched onto the wire.

In the form shown in Figs. 8, 9 and 10, the lugs, 12, for embedment in the soft metal are struck up, two at each side out of and forming apertures, 11, 11, therein, the apertures struck out of each aperture being cut at the line, 11, and the two portions thus severed being folded up at opposite sides of the disk, the corresponding lugs out of the two apertures being turned up at the same side of the disk so as to face each other and being rendered stapleelike by having cord apertures, 13, which are alined with each other, and the cord aperture, 3, in each boss is formed extending through these apertures, 13, 13, of the lugs, 12, so that when the cord is inserted through the cord-apertures of the bosses, it extends also through the cord ap ertures of the hard metal lugs, and when the bosses are clenched down upon the lugs, the edge of the aperture of the hard metal lug bites into the cord and thereby engages it there securely. Of the three forms shown this is the preferred form. In this form it is not considered necessary that the bosses, 2, 2, should entirely cover the apertures, 11, formed by striking up the lugs for embedme-nt in the bosses, but the bosses sufliciently over-hang the apertures so that the soft metal is continuous through the apertures from one lug to the other, and is thereby inseparably engaged with the disk.

In all the forms shown the hard metal disk is designed for receiving a permanent identifying mark such as the initials of the name of the transportation company or other concern having the custody of the sealed package and responsible for the affixing of the seal. The clenching of the bosses upon the cord or wire is performed in the usual manner by pliers which will be constructed so as to leave a special imprint upon the clenched boss which will usually be the means of identifying the particular persons by whom, or place at which, the package was sealed.

For some purposes it is preferable to supply the seal with means for bearing a more extended permanent mark for identifying number or character, and for this purpose the form shown in Fig. 6 may be provided in which the hard metal disk has an eX- tended lug or tag member, 10, impressed with an identifying number or other character.

I claim:

1. A seal comprising a hard metal disk and soft metal bosses projecting from'opposite sides of the disk, said bosses having respectively, at said opposite sides of the hard metal disk, meansfor holding opposite ends of a securing wire or cord; whereby the hard metal disk becomes located between said two end portions of the securing wire; one of said bosses being adapted to have the securin wire or cord inserted throu h it b b and to be pressed thereon.

2. A seal comprising a hard metal disk and soft metal bosses on the opposite sides of the disk, the hard metal disk having lugs struck up and bent out from its body and embedded in the soft metal bosses, such bosses having each an aperture extending adjacent to said lugs for receiving a wire or cord to be engaged by compressing the substance of the lugs thereonto.

3. A seal comprising a hard metal disk having staple-like lugs struck out from its substance at its opposite sides, and soft metal bosses at the opposite sides of such disk in which such staple-like lugs are embedded, the bosses having apertures extending through them in planes substantially parallel to the plane of the disk, and taking through the apertures of said staple-like lugs, respectively, for receiving wires or cords to be engaged by the compression of the bosses and lugs thereonto.

4. A seal comprising a hard metal disk having struck up from its substance and projecting at its opposite sides, lugs which overhang the aperture from which they are struck, and soft metal bosses at said opposite sides of the disk embedding such lugs, the bosses and apertures extending through them in position to be overhung by the lugs embedded in said bosses for receiving wires or cords to be engaged by the compression of the bosses and lugs thereon.

In testimony whereof, I have hereunto set my hand at Chicago, Illinois, this 12th day of September, 1912.
